PhotoBioCure™ technology is based on biopolymers that turn from a sticky liquid into a flexible solids under the influence of UV radiation. This feature allows forming customized implants, adjusted to tissue defects, in situ in vivo. Importantly, the composition is biodegradable in the in vivo environment and eventually replaced by natural tissue.

An important competitive feature is the ability to inject of the material through small incision (like in laparoscopic techniques). At the same time, the high viscosity of our biomaterial eliminates the need for sutures, which can be technically challenging and time-consuming, especially within a minimally invasive procedure. Our biomaterials can be also bioactive as they degrade within the in vivo environment in a controllable process, thus facilitating tissue regeneration.

About Us

POLTISS (Polymer Tissue) was founded in 2015 to introduce PhotoBioCure™ technology of modern, light activated, adhesive polymer biomaterials to the market.

We aim to improve comfort of patients and surgeons with our programmable biopolymers.

Our technology is based on polymeric materials, which under the influence of UV radiation turns from a sticky liquid into flexible solids. The composition is fully degradable in a living environment and eventually replaced by natural tissue.

PhotoBioCure™ properties are especially relevant to minimally invasive surgery that is increasingly performed to reduce postoperative complications, recovery times, and patient discomfort.
